Silicon PU court and manufacturing method thereof

Abstract

The invention provides a silicon PU court and a manufacturing method thereof. The court comprises a base plane, a primer layer coated on the base plane, an elastic layer positioned on the primer layer, a reinforcing layer coated on the elastic layer, a surface layer coated on the reinforcing layer, and at least one primer reinforcing layer arranged between the primer layer and the elastic layer. According to the invention, the reinforcing layer is added on the primer layer. With the cooperation of glass fiber mesh cloth and primer PU glue, the mesh cloth is applied on the surface of the base plane; with the high-strength tensile force of the fiber, the elastic layer bottom layer is not swelled due to water vapor rising of the base plane. Therefore, a base bubble problem of the silicon PU court is solved.

Description

technical field [0001] The invention relates to a silicon PU court and a manufacturing method thereof, in particular to a non-foaming silicon PU court and a manufacturing method thereof. Background technique [0002] Silicon PU court is an environmentally friendly court made by combining physical and chemical methods. It has good cushioning and ductility, and is easy to construct and maintain. However, the basic foaming of silicon PU courts has always been an unsolvable problem in the industry. Technical problems, especially in winter and spring due to the low temperature and abundant rain, resulted in a very long foundation maintenance period, which seriously affected the construction period. Under normal circumstances, the cement foundation often takes more than one month to dry completely, and it cannot be completely dry for two months in winter or spring. If the judgment is not accurate, small bubbles will still appear after the construction is completed. The more troubl...

[0002] Silicon PU court is an environmentally friendly court made by combining physical and chemical methods. It has good cushioning and ductility, and is easy to construct and maintain. However, the basic foaming of silicon PU courts has always been an unsolvable problem in the industry. Technical problems, especially in winter and spring, due to the low temperature and abundant rain, the basic maintenance period is very long, which seriously affects the construction period

Under normal circumstances, the cement foundation often takes more than one month to dry completely, and it cannot be completely dry for two months in winter or spring. If the judgment is not accurate, small bubbles will still appear after the construction is completed. The more troublesome problem is foaming. Afterwards, it is very difficult to repair. If a small area can be needled or cut off the bubble area and repaired under the hot sun, the color difference between the repaired place and the original one is very obvious and ugly
